К сожалению задать кнопкам другую функцию не представляется возможным, так как мышь работает со стандартным драйвером системы. Специальной программки, которая позволила бы изменения функций кнопок, в комплекте не прилагается.  

Можно посмотреть в интернете, может быть можно скачать программку для программирования кнопок

Вот например с этого сайта http://www.highrez.co.uk/downloads/XMouseButtonControl.htm

Но заметьте, что это неофициальное решение и мы не можем дать гарантии, что данное ПО вообще будет работать с данной мышью.

If the lighting of the product does not turn off when the PC is turned off, we recommend that you check the settings of the USB port. Some computers continuously power the USB ports even when the computer itself is turned off.

• Try using the mouse on a different surface or use a mousepad.
• Clean the sensor on the bottom of the mouse with a dry cloth.
